windows下python2中文编码问题

# -*-coding: utf-8-*-
import sys
reload(sys)
try:
    sys.setdefaultencoding('utf-8')
    print ">>>>>ok"
    print sys.getdefaultencoding()

except Ecxeption as e:
    print "*******", e
    

with open(r'C:\Users\marvel\Desktop\中一去.txt'.decode('utf-8'), 'r') as f:
    print f.read()

以上代码可以正常使用中文
